TOOL FOR INSTALLING TURPENTINE-CUPS.

Specification of Letters Patent.

Patented Sept. '16, 11913.

To all whom. it may concern Be it known that l, Gannon C. Pomona, acitizen oi the United States, residing at lliloxi, in the county ofllarrison and Eritate of itlississi 'ipi, have invented a new and usefultool for Installing Turpentinee ups, of which the following is aspecification.

This invention relates ;enerally to turpentine tools, and particularlyto a tool adapted 'toinstalling turpentine cups.

l'leretolt'ore, in order successfully to prepare the tree faces for thereception of a. cup. it has generally been necessary to employ twoax-men for the purpose, one rightand the other letbhanded, and usingaxes particularly adapted for their respective wi-elders. This is due tothe :t'act that ambidextrous ax-men are scarce, and that the averageaxanan has trained himself to work trom one side only. As is well known,right-handed axunen predominate in munbers, and so it frequently happensthat an operator or contractor cannot supply himself with a leitt-lmndedone, the result being that he is hampered in his work and loses muchvaluable time for which he has to pay for the services of unskilled andthus unsatistactory labor.

it is the object of the present invention, in a novel and practicalmanner, to obviate the above objections by providing a tool that shallbe adapted to be used by either a right. or a left-handed arc-man, theconstruction oil which will materially :t'acilitate the operation andlessen the labor of forming the tree faces, and which shall reduce tothe minimum the danger of cutting too deep and thus injuring the trees.

Nith the above and other objects in view, as will appear as the natureof the invention is better understood, the same consists in the novelCOl'lStl'llCtlOn and combination of parts of a turpentine tool, as willbe hereinafter fully described and claimed.

In the accompanying drawing forming a part of this specification, and inwhich like characters of reference indicate corresponding parts, Figure1 is a View in perspective of a tool constructed in accordance with thepresent invent-ion. Fig. 2 is a longitudinal sectional view. Fig. 3 is atransverse sectional View on the line 83 of Fig. 2. Fig. 4: is a rearelevation of the tool.

The tool comprises a cutting head designated generally .t, a shank Q,and a neck connecting the head and the shank. As shown in Fig. 13, thecutter head comprises a straight 'lront cutting edge 4- and a pair atcurved lateral cutting edges 5, that merge into the neck 3, the lattercoinstituting a continuation ol the shank .2, which is disposed inapproximate parallelism with the front edge -t-. The cutter head is avhollow structure of an approximately irregular elliptical torn),providing thereby ample space for the escape 01 chips in the use oi thetool, whereby any loss of time which would result from clogging isprevented.

()ne ol the essential 'teaturcs of the invention is the manner ofdisposing the side cutting edges 5 relative to the "front. cutting edge,the former edges, as shown in Fig. 2, being disposed approximately at anangle of 14) degrees to the trout cutting edge (3, so that a cleaninitial cut, known as the lirst streak may be formed, which will a.:curately define the limit of the lat eral cut, in one direction oilthe lace.

The cutting edges 5, as shown in Fig. l, terminate some distance shortof the neck, thus further to permit the escape of chips.

The cutter head as a whole is combined with a handle 7 having adjacentone end an all-through slot; 8 in which the neck tits, the shank beingdisposed within a longitudinal channel 9 arranged in the handle on theside opposite that through which the neck is inserted, the inner wall 10ot' the channel being shaped in such manner as to conform to theadjacent; portion of the shank. By this arrangenlent it will be seenthat the force of the impact resulting from the use 01' the tool willhave a teiulency always to seat the shank in the channel, so thataccidental disconnection of the parts in use will positively beprecluded.

As will be obvious, in order to secure the above results, the cutterhead as a whole should be comparatively thin, and to impart the desiredweight to the tool to enable it to deliver etleetive blows, the handlehas combined with it at the end opposite that carrying the head, aspherical weight 11, which will in effect secure the same -function asif the head were made of thick metal.

In the use of the tool, the ax-man cuts his first streak, say on theleft hand side Off the center line of the two faces, this cut resemblinga half-auger hole, and the straight cutting edge of the tool is thenbrought into play and will remove the bark up to the point which will beconsidered the median line of the two faces, and the operation is thenrepeated on the right hand side, and when the two faces are cleared ofbark, the two incisions to receive the turpentine gut-- ter are madewith the straight edge of the cutter head in the same manner as that ac-Owing to the shape of the tool, it will beadapted to be used as ascraper, thus materially broadening the scope of its utility.

It will be noted that the side portions of the head converge backwardlytoward the shank and they thus constitute means for abutting against oneside of the handle while the shank is engaging the opposed side thereof.Thus the head of the tool is prevented from sliding toward or away fro-mthe handle. Furthermore, as the inclined lower edges of the headconverge upwardly toward the shank, it will be seen that they permit thehead to be tilted downwardly toward the handle, thus to permitwithdrawal of the shank from the handle.

I claim:

The combination with a handle, of a cut ting element comprising, in aone piece structure, a shank, a cutting head thereon having a straightfront face and side portions converging from the front face to theshank, said straight front face having a straight cutting edge and theside portions being formed with inclined cutting edges converging towardthe shank and disposed in a plane that approximates an angle of 45degrees to the straight front face of the cutting head, the cutting headand shank being connected by a straight neck disposed at right angles tothe shank and adapted to be removably seated in the handle, said shankconstituting means for engaging one side of the handle and saiddiverging side portions constituting abutments for the other side of thehandle, to hold the head against sliding movement toward or away fromthe handle, the inclined lower edges of the head constituting means forpermitting clownward tilting of the head relative to the handle and thewithdrawal of the shank from the handle.

In testimony that I claim the foregoing as my own, I have hereto atlixedmy signature in the presence of two witnesses.
